Collapses:
  • Windows Mobile a branch that was previously expanded in a TreeView Table control. The "child" nodes are no longer visible in the TreeView Table control. The child nodes remain in their previous status (collapsed or expanded).
  • a break that was previously expanded in a Table control. The break elements are no longer visible in the Table control.
Reminder: At run time, a node is collapsed when the "+" sign is found in front of the name of the node.
Versions 22 and later

Example
Windows Mobile
// Collapses the selected branch in the TreeView Table control
TVT_Schedule.Collapse()
Windows Mobile
// Collapses the "TVT_Schedule" TreeView Table control
TVT_Schedule.Collapse(1)
// Equivalent to: TVT_Schedule.CollapseAll()
Windows Mobile
// Collapses the specified branch in the TreeView Table control
TVT_Schedule.Collapse("MyRoot" + TAB + "MyBranch")
// Collapses the break of the current row in the "TABLE_Break" Table control
TABLE_Break.Collapse(TABLE_Break)
Syntax

TreeView Table: Collapsing a branch while specifying the row number Hide the details

<TreeView Table control>.Collapse([<Row number>])
<TreeView Table control>: Control name
Name of TreeView Table control to use.
<Row number>: Optional integer
Number of the row containing the branch to collapse. The branch found in the current row is collapsed if this parameter is not specified.
Windows Mobile

TreeView Table: Collapsing a branch while specifying its name Hide the details

<TreeView Table control>.Collapse([<Branch name>])
<TreeView Table control>: Control name
Name of TreeView Table control to use.
<Branch name>: Optional character string (with quotes)
Name of branch to collapse. This parameter has the following format:
"<Name of root>" + TAB + ["<Name of 1st node>" + TAB + ...
["<Name of 2nd node>" + TAB + [...]]]"<Branch name>"
A WLanguage error occurs if this parameter does not correspond to an existing branch.
The branch found in the current row is collapsed if this parameter is not specified.
If two branches correspond to the specified path, only the first one is collapsed.

Table with breaks: Collapsing a break Hide the details

<Table control>.Collapse([<Row number> [, <Name of break>]])
<Table control>: Control name
Name of Table control to use. This control must have one or more breaks. Otherwise, this function has no effect.
<Row number>: Optional integer
Number of the break row to collapse. This number must corresponds either to the number of the current row or to the number of the first row of break to collapsed. If this parameter is not specified, the break of current row is collapsed.
<Name of break>: Optional character string
Name of break to collapse. This parameter must be specified in case of nested breaks. It allows the break that will be collapsed to be defined. By default, no break is collapsed if the breaks are nested.
Remarks

Use conditions

TableEnroule_objet can be used in:
  • Windows Mobile a TreeView Table control.
  • a memory Table control.
  • a browsing Table control loaded in memory.
This function cannot be used on the browsing Table controls (direct access).

Branch to collapse

TableEnroule_objet has no effect:
TreeView Table controlTable control with breaks
  • if the branch to collapse is not found.
  • if the branch to collapse is a leaf.
  • if the branch to collapse is already collapsed.
  • if the Table control contains no break.
  • if the Table control contains several breaks and the break to collapse is not specified.
  • if no row is selected in the Table control and if <Row number> is not specified.

Note for the TreeView Table controls: If <Row number> or <Branch name> corresponds to the branch in the first row, the entire hierarchy of the TreeView Table control is collapsed (equivalent to <Table>.CollapseAll).

Selection bar

For the TreeView Table controls:
  • If the selection bar was positioned on one of the elements of the node to collapse, the bar is positioned on the collapsed node after the call to TableEnroule_objet.
  • The modification code is called whenever the selection bar is moved. If two levels are collapsed and if the selection bar is positioned on the higher node, the modification codes of each level are run.
For the Table controls with breaks, the selection bar is not modified. It stays on the current element even if the break is collapsed.

Runtime speed for the TreeView Table controls

The runtime speed of syntax 1 is faster than the runtime speed of syntax 2.
